When you eat yogurt, it’s probably because you want to drop a few pounds or snack on something tasty and refreshing. But, if you are a mouse at least, your favourite bacteria culture treat could also give you huge testicles.
That’s what biologists at MIT discovered when they were testing the effects of yoghurt on obesity. They fed three groups of mice high-nutrient yoghurt, standard mouse food and low-nutrient food meant to stand in for the crap we the morbidly-obese public consumes. Not surprisingly, eating healthily produced the best results: The yoghurt eaters had “luxuriantly silky fur” and “projected their testes outward, which endowed them with a certain ‘mouse swagger’”. Mouse swag!
The male yoghurt eaters were also found to have five per cent larger testicles than the mice who ate normal food, and 15 per cent larger than the junk food eaters. And it’s not just for show: the yoghurt-engorged mice also showed a higher rate of insemination and produced more young per pregnancy. So the swag is justified! If we justify swag by big families and large, thrusting mouse testes. [Scientific American]
